Method for holding brazing material during a brazing operation

Abstract

A method for holding a sintering filler material during a brazing/sintering operation for repairing a damaged area of a component wherein the component is in either a bonding face down position, bonding face vertical position or bonding face up position. The method includes providing a wire mesh and attaching the wire mesh to the component in a location corresponding to the damaged area. Further, the method includes forming a gap between the wire mesh and the component. Moreover, the sintering filler material may be inside the wire mesh or both inside and outside the wire mesh in order to secure the sintering filler material to the damaged area.

What is claimed is: 
     
         1 . A method for holding a sintering filler material during a brazing/sintering operation for repairing a damaged area of a component, comprising:
 providing a wire mesh;   attaching the wire mesh to the component in a location corresponding to the damaged area; and   pushing sintering filler material through the wire mesh to insert the sintering filler material between the damaged area and the wire mesh in order to attach the sintering filler material to the damaged area.   
     
     
         2 . The method according to  claim 1  wherein the component is in a bonding face down position. 
     
     
         3 . The method according to  claim 1  wherein the component is in a bonding face vertical position. 
     
     
         4 . The method according to  claim 1  wherein the component is in a bonding face up position. 
     
     
         5 . The method according to  claim 1  further including cleaning the damaged area by performing a fluoride ion cleaning procedure or by mechanical blending. 
     
     
         6 . The method according to  claim 1  wherein the sintering filler material includes a multi-layer filler structure. 
     
     
         7 . The method according to  claim 6  wherein the multi-layer filler structure includes a putty/putty two layer configuration. 
     
     
         8 . The method according to  claim 6  wherein the multi-layer filler structure includes a plural layer putty-powder/slurry configuration. 
     
     
         9 . The method according to  claim 1  wherein the wire mesh is attached to the component by a fusion welding method. 
     
     
         10 . The method according to  claim 1  wherein the wire mesh is fabricated from a material which is metallurgically compatible with sintering filler material. 
     
     
         11 . The method according to  claim 1  wherein a gap is formed between the wire mesh and the component. 
     
     
         12 . A method for holding a sintering filler material during a brazing/sintering operation for repairing a damaged area of a component wherein the component is in either a bonding face down position, bonding face vertical position or bonding face up position, comprising:
 attaching a first quantity of sintering filler material to the damaged area;   positioning a wire mesh over the first quantity of sintering filler material;   attaching the wire mesh to the component in a location corresponding to the damaged area such that the wire mesh is on top of the first quantity of sintering filler material and secures the sintering filler material to the damaged area.   
     
     
         13 . The method according to  claim 12  further including cleaning the damaged area by performing a fluoride ion cleaning procedure for the component or localized mechanical blending on the damaged area. 
     
     
         14 . The method according to  claim 12  wherein the sintering filler material includes a multi-layer filler structure. 
     
     
         15 . The method according to  claim 14  wherein the multi-layer filler structure includes a putty/putty two layer configuration. 
     
     
         16 . The method according to  claim 14  wherein the multi-layer filler structure includes a plural layer putty-powder/slurry configuration. 
     
     
         17 . The method according to  claim 12  wherein the wire mesh is attached to the component by a fusion welding method. 
     
     
         18 . The method according to  claim 12  wherein the wire mesh is fabricated from a material which is metallurgically compatible with sintering filler material. 
     
     
         19 . A method for holding a brazing tape during a brazing/sintering operation for repairing a damaged area of a component wherein the component is in either a bonding face down position, bonding face vertical position or bonding face up position, comprising:
 providing a wire mesh;   positioning the brazing tape in a location corresponding to the damaged area;   positioning the wire mesh over the brazing tape; and
 attaching the wire mesh to the component to hold the brazing tape against the damaged area. 
   
     
     
         20 . The method according to  claim 19  wherein the wire mesh is attached to the component by a fusion welding method. 
     
     
         21 . A method for holding a sintering filler material during a brazing/sintering operation for repairing a damaged area of a component wherein the component is in either a bonding face down position, bonding face vertical position or bonding face up position, comprising:
 attaching a first quantity of sintering filler material to the damaged area;   positioning a wire mesh over the first quantity of sintering filler material;   attaching the wire mesh to the component in a location corresponding to the damaged area such that the wire mesh is on top of the first quantity of sintering filler material; and   attaching a second quantity of sintering filler material onto the wire mesh.
